慢性咳嗽患者气道反应性测定的意义

目的探讨测定咳嗽患者气道反应性的方法和意义。方法对仅有咳嗽症状,持续3周以上,无体检及X线检查阳性发现的患者,采用氧气驱动的雾化吸入器,吸入10%氯化钠灭菌溶液,以峰流速仪测定最大呼气流速,观察其下降值和氯化钠消耗量。结果测定患者68人,阳性26人,平均雾化量3.47ml。受试者多可耐受。阳性者用支气管扩张剂可缓解症状。结论雾化吸入氯化钠测定气道反应性对慢性咳嗽的诊断治疗有一定指导意义,方法简捷,适于基层医院推广。

The Significance of Measuring Bronchial Responsiveness to the Patients with Chronic Cough

Objective To explore the value and method of measuring bronchial responsiveness of patients with chronic cough.Methods The patients with chronic cough for three weeks or more were choiced,and who have no physical examination and chest X-ray abnormal.The nebulized solution was drived by oxygen and 10%sodium chloride was inhaled.The peak expiratory flow (PEF) and the consumption of hypertonic saline were observed.Results 68 cases were surveyed.Among them 26 cases showed positive reaction.An average consumption was 3.47ml.The most subjects were tolerant of the test.The cases who showed positive reaction can be remitted by bronchodilator.Conclusion The method of measuring bronchial responsiveness by inhaling hypertonic saline is a certain guiding value to clinical diagnosis and treatment of chronic cough,and which is a simple and rapid one that is suitable for being spreaded in primary hospitals.
